BODY W A TER - WHY MEASURE IT? Body water is the single most important
component of body weight. It repr esents over half of y our total weight and almost
two thirds of y our lean body mass (predominantly muscle). W ater performs a
number of important roles in the body: All the cells in the body , whether in the skin,
glands, muscles, br ain or anywhere else, can only function pr operly if they have
enough water . Water also plays a vital part in r egulating the body’s temperatur e
balance, particularly thr ough perspiration. The combination of your weight and f at
measurement could appear to be ‘normal ’ but your body hydr ation level could be
insucient for healthy living.

For those using Athlete Mode: no te that athletes may have a lower body fat r ange
and a higher body water range than shown above, depending on their type of sport
or activity . Body water measurement r esults ar e influenced by the proportion of body
fat and muscle. If the pr oportion of body fat is high, or the pr oportion of muscle is
low then the body water results wil l tend to be low. It is important to remember that
measurements such as body weight, body f at and body water are tools for you to use
as part of your healthy lif estyle. As short term fluctuations are normal, we suggest
you chart your pr ogress over time, rather than focus on a single days r eading.

WHY SHOULD I KNOW MY MUSCLE MASS? A ccording to the American College of
Sports Medicine (ASCM), lean muscle mass may decr ease by nearly 50 percent
between the ages of 20 and 90. If y ou don’t do anything to replace that loss you’r e
losing muscle and increasing fat. It is also important to know y our muscle mass
% during weight reduction. At rest, the body burns appr oximately 110 additional
calories for each kilo of muscle gained. Some advantages of gaining muscle mass
include:
• Reversing the decline in str ength, bone density and muscle mass that
accompanies age
• Maintenance of flexible joints
• Guide weight reduction when combined with a heal thy diet.
This product is for domestic use onl y. Pregnant women should onl y use the weight

CAUTION : Do not use this pr oduct if you have a pacemak er or other medical device
fitted. If in doubt, consult y our doctor .
WHA T DOES MY BMI V ALUE
MEAN? Body Mass Index
(BMI) is an index of weight-
for-height that is commonl y
used to classify underweight,
overweight and obesity in
adults. This scale calculates
your BMI value for you. The
BMI categories shown in
the chart and table below
are r ecognised by the WHO
(World Heal th Organisation)
and can be used to interpret
your BMI value.
Y our BMI category can be
identified using the table
below .
BMI Category BMI Value Meaning Health Risk Based Solely On BMI
< 18.5 Underweightt Moderate
18.6-24.9 Normal Low
25-29.9 Overweight Moderate
30+ Obese High
IMPORT ANT: If the chart/table shows that y ou are outside of a ‘normal ’ healthy
weight range, consult your doctor befor e taking any action. BMI classifications ar e for
adults (age 20+ years) onl y .
BASAL MET ABOLIC RATE (BMR) - WHA T DOES IT MEAN?
Y our Basal Metabolic Rate (BMR) is an estimation of the energy (measured in
calories) expended by the body , at r est, to maintain normal body functions.This
continual work makes up about 60-70% of the calories the body uses, and includes
the beating of your heart, r espiration, and the maintenance of body temper ature.
Y our BMR is influenced by a number of factors, including age, weight, height, gender ,
dieting and exercise habits.
BONE MASS - WHY MEASURE IT? Regular exer cise and a balanced diet can help
maintain healthy bones. Like muscle, bone is a living tissue that can r espond to
exercise b y becoming stronger . For most people, bone mass peak s during their
thirties. After that time, we can begin to lose bone. Regular ex ercise can help pre vent
that loss. Calcium and vitamin D contribute to health y bones. Good sources of these
are dairy pr oducts, green leafy vegetables and fish.
The bone mass readings given by this pr oduct are an estimation of the amount of
bone in your body . Those with osteopor osis or low bone densities may not get
accurate estimations. If y ou have concerns regar ding your bones you should al ways
consult your doctor .
QUESTIONS & ANSWERS
How exactly is m y body fat and water being measured? This Sal ter Scale uses
a measurement method known as Bioelectrical Impedance Anal ysis (BIA). A minute
current is sent thr ough your body , via your f eet and legs. This curr ent flows easily
through the lean muscular tissue, which has a high fluid con tent, but not easily
through fat. Therefor e, by measuring your body’s impedance (i.e. its resistance to the
current), the quantity of muscle can be determined. Fr om this, the quantity of fat and
water can then be estimated.
What is the value of the current passing thr ough me when the measurement
is taken? Is it safe? The curr ent is less than 1mA, which is tiny and perfectly safe.
Y ou will not be able to feel it. Please note however , that this device should not be
used by anyone with an internal electr onic medical device, such as a pacemaker , as a
precaution against disruption to that device.
If I measure my body fat and wa ter at dierent times during the day , it can
vary quite considerably . Which value is correct? Y our body fat percentage
reading varies with body water content, and the latter changes thr oughout the course
